This bond is made between close friends (who are of no relation). This oath causes no permanent damage. There is no limit to the number of characters you make part of your family.

The characters begin by cutting their right palms and clasping hands as they recite the oath making sure the blood mingles.

If a character directly (or indirectly) harms his blood brother/sister, the character suffers the equivalent of a talent crisis. Also, these two characters can be affected like family (see p.28 Horrors).
