Spell Haven: From Dragonmarked, it requires a Dragonmark of any grade (Aberrant or True), but it's a lower-level Contingency. Even better, it doesn't override existing Contingencies. The downside is the spells you can use with it are limited by your Dragonmark's grade, to a maximum of 5th level for a Greater dragonmark. Oh, and it's open to Clerics and Bards, not just Sor/Wiz. I'll post the spell itself if asked, since it's a tad useful.
