Flame Altar
The Flame Altar marks the spot for a base. Any changes made within the boundaries of the Flame Altar are permanent, unless the Altar is extinguished. Changes made outside the Altar’s boundaries, however, will reset after 30 minutes or upon a game restart.

Removal
To remove a Flame Altar, interact with it, select the "Deactivate Altar" option, and confirm. This starts a 30-second timer, during which the removal can be cancelled. After the timer expires, the Flame Altar disappears. Built structures, placed items, and terrain changes within the Altar's boundaries will remain in place until the area resets, which occurs after 30 minutes or upon a server restart. Placing a new Flame Altar before the reset will restore protection to the area, but the new Altar will not inherit any size upgrades from its predecessor. Note that the Flame Level remains a global constant, even if all Flame Altars are extinguished. The Flame Level can never decrease.
Renaming
To rename a Flame Altar, interact with the Flame Altar, press R, and enter a new name for that specific Altar.
