Markings

Objects of this type are practically always permanent fixtures of areas that characters may not pick up. Markings are most commonly used as signposts and/or to open doors, sometimes only for characters of one specific class.

All markings have four type-specific values: one specifies how high-level a character must be to see it, another specifies other restrictions on its visibility (like only those who have practiced rogue lore or only those who are affected by detect hidden may see it), another specifies which door in its room (if any) it affects when it is pushed or pulled, and yet another specifies exactly how this door will be affected by such usage (like being opened or being locked).

One good example of markings are Midgaard's "thief marks," which serve to help rogues to find their guildmaster.
