Alter Aeon FAQ (Frequently Asked Questions)

FAQ 19.3 - If a room has a fire in it, it should be an object

While most static features in rooms, such as furniture, decor, rugs, etc.
do not need to exist as objects, campfires, firepits, fireplaces and other
features that involve open flame that might be reasonably used to heat
and cook with should be made as objects of the FIRE type, typically with
NO_SAC and NO_TAKE flags.

This adds a passive regeneration effect for resting and sleeping
characters in a room, and also allows characters to use the cooking skill.

If you find a room where the long description mentions a fire and there
is no such object, it is appropriate to add one or typo log it for the
responsible builder to handle.
