Important locations around Dragonstone

Court
Cycle 6's Outside View of Court
The Court's purpose is to settle disputes amongst those in Dragonstone. The court is large and features a lava pit in the center that is only accessible through an iron door. The court can be found using /warp court. It is also connected to the white bridge that connects to the forge, shops, and PVP arena.
Additional: The Court is now controlled by an AI, and is in a Magic Suppressed Zone.
Documentation of past court cases can be found here.

Dragon Forge
The Dragon Forge is used to make powerful weapons and tools. The forge can be traveled to with /warp forge. It is also connected to the white bridge that connects to the shops, court, and PVP arena. There are 3 types of forges, although only the Aether Forge is currently usable. The other 2 types are the Draconic Forge and the Hellstone forge. The forge uses materials often found in dungeons. This is considered "end game" content and it is suggested that you complete vanilla survival before diving into the forge. 
Other information on the forge can be found in the Dragon Forge book.

Dungeon Portal Room
The Dungeon Portal Room can be accessed with /warp dungeons or by hopping over some mushrooms from spawn. The Dungeon Portal Room is a place where you and your team (optional) gather and prepare to brave the dangerous challenge that is the dungeons. This is where you can collect a majority of forge materials to use later. Some dungeons are marked Easy, such as the Tutorial Dungeon, and Happy Hills. Others are labelled Medium, with the latest dungeon Outpost falling under this category. Further difficulty levels will become available when other dungeons are released. Dungeons can require a few resources to succeed. The quality of your armor, weapons, and food of choice will be pivotal in deciding your victory. For example, The Outpost recommends max enchanted diamond armor (However, netherite is strongly suggested) as well as a matching sword to be able to take a stand, although the Aether Blade is strongly preferred for its bonus damage against the undead. 
Having more teammates increases the quality and quantity of loot, while also increasing difficulty.
Full Dungeon Guides can be found in the Dungeon Codex book.

The End
The End has been explored and conquered by many players and is now facing cosmetic reconstruction to make it look stunning. The End is often visited by players to use the public enderman farm and enchanting table. The farm has enderman fall and leaves them one hit away from death, allowing players to collect XP and repair their mending items. The End can be found by going through the public nether portal off of spawn and going south in the nether hub to an ice path. This path leads to public end portal.
Public end portal:

The Nether Hub
This beautiful hub is located in the Nether. You can travel to it by going through the public Nether portal, located south of spawn within the warzone.

The Overworld
The Overworld
This particular world has been graced with Dragon's presence, with his abundant knowledge and magical skills he has blessed it with special items obtainable through entering dungeons (which is directly behind spawn) and forging the materials at /warp forge.
Coolham123's home
The Overworld is the dimension the player first spawns in. Often venturing around exploring the bountiful lands, quickly finding the first house built on this reset by the admin coolham123. While perusing his home they find his lectern most often turned to the page 6 of 9 (nice!) which states stealing place blocks is against the rules next to the shiny diamond blocks. This is something called "A test". In this case it is to see if the likely new player has read the rules and won't steal the shiny diamond blocks. If they fail, they often get jailed, leaving them plenty of time to do /rules and read upon why they were jailed. 

PVP Arena
The PVP Arena, although not used very often, is a place where all players, regardless of their reason may combat one another, it is important to note that the area is Keep Inventory so no need to worry about losing your shinies! Other players can watch from above on barrier blocks that provide a birds-eye view of the battles below. This arena can be found using /warp arena. It is also connected to a white bridge that leads to the court, forge, and shops.

Shops
The shopping area can be accessed with /warp shop. It is also linked by a white bridge to Court, the Forge (dshop), and the Arena. Players can enter a shop and interact with the shopkeeper (almost always a villager, but sometimes there's endermen) to view trades and purchase items. Customers cannot view a shop's inventory, which is contained within a chest, which the villager keeps locked. Only the owner of that chest can open it and edit the villager's appearance and trades. Common currencies include Iron Ingots, Diamonds, Shard Dust, and Dragon Shards, however any item can technically be used as currency.
There are 2 types of shops: Island shops (4 total) and regular shops (29 total). The regular shops are split into 4 themed areas: Mushroom Island, Ruins, Volcano Island, and Casino Island.
Some shop examples:
Current Island Shops:
Sunset's Sand Castle (constructed by Rota)
Shulker Shop Island( Ran by MENTOS, Iron, and lmt77)
Femboy Hooters (Ran by Maliah and additional staff)
Eshat's Oasis (Ran by Eshat)

Spawn
All coming travelers start off at spawn. You can also teleport here with /spawn. The spawn is located at 0,0 in the sky. There are four different paths you can go from spawn. Going south from spawn will send you launching into the sky and either off the platform, or into the RTP Portal.  West of spawn you will find grief examples. The grief examples show you what is and what isn't allowed on Dragonstone. East you will find the Top Donators of this current cycle. North you will locate the Staff Room If you choose to drop off the platform you will land in the warzone. There you can find the public nether portal.

In earlier cycles, spawn used  to have The Dungeon Portal Room. However, as the current cycle, it was removed.
Going North East you will find...
Usur Island!
Usur Island has the greatest qualities of almost any resort, like a pool, (with a very tall diving board), relaxing chairs, and a Bar where the only refreshment (served by a camel) is Sprite Cranberry! 
Usur Pool:
The Bar:
note: usur is not responsible for any effects gained by drinking from the bar, or from jumping off the diving board.

The Void
The place the server sends you while it's magic recharges. Many report of having incredibly powerful enchants in this location.  Players often fight here as there is nowhere to run nor nowhere to hide along with the fact there are plenty of custom abilities. It is said that more valuable materials can be found the higher you climb.
Dragon using his powers has gifted a fraction of his powers to certain players to help maintain the disguise of Dragonstone. With his gift they became powerful beings sworn to not disrupt the actions of the average player only to maintain passage between the islands he put in there for the players to enjoy. These players bear a pickaxe symbol by their username. 
 

Warzone
This is the zone between spawn and the general server. In previous versions such as 1.17.
There was a more notable difference between it and spawn however in 1.18 it's start is indicated by red wool and end by blue wool.
