Waethra's warm welcome

Waethra's Warm Welcome was a multi-schooled arcane spell that protected a given area from intrusion by magical or inter-dimensional means.

Effects
When cast, this spell affected an area extending out from the caster at a radius of at least 170' (51.8 m). This space flickered with magical light during the spell's casting but was otherwise imperceptible afterwards.

Any being that attempted to travel through that area, by means of transportation magic, psionics or by traveling along the astral or ethereal planes, were halted, diverted and eventually returned to their original location.

The 'intruder' affected by Waethra's warm welcome was first to an extra-dimensional space of near-complete darkness, illuminated only by a number of magic missile-like projectiles. They fell through this area for a matter of seconds and were struck by a number of these arcane bolts. Eventually, the intruder was returned to their plane of origin, 70' (21.3 m) above their original location, that is, wherever they crossed to analogous plane or engaged in their translocation spell.

The spell affected a number of beings relative to the skill and power of the caster.

Components
The material components for this spell included two daggers, a thread of spiderweb, an eye of a phase spider and a small amount of ichor taken from an astral dreadnought.
