These are loosely based on AD&D spells.
IQ 12
Hidey-Hole (S) [5] (WARD): this spell creates an extra-dimensional space large enough for one person (and everything he is carrying). This space is neither to warm, nor to cold for the caster and allows him to rest comfortably and securely for the duration of 8 hours. Any spell that would warn the caster of danger functions while the caster is in his hidey-hole. The caster can create a hidey-hole for another character as well. Casting a detect magic on the hex where the entrance to the Hidey-Hole is will reveal the fact that there is magic there, but not the spell used. Reveal Magic would identify the Hidey-Hole for what it is, but a caster would need to know the exact location of the entrance to target it with the Reveal Magic.

IQ14
Hidey-Haven (S) [10] (Hidey-hole): This spell creates an extra-dimensional space large enough for 4 people, otherwise it functions exactly the same as Hidey-hole with the same duration.

IQ16
Protected Refuge (S) [15] (Hidey-hole, Unnoticeability): This creates an extra-dimensional space large enough for 8 people that cannot be found. It functions like a Hidey-Hole except that the duration is 24 hours.

These spells do have Prerequisites, which is rare for spells, but this is to reflect the amount of magical knowledge needed to learn these spells.

D'oh! An animal or character that can track by scent could find the entrance.
