Celestial Pyre

You can cast this spell only at night. You memorialize a dead creature you touch, turning it into a constellation, provided that it has been dead no longer than 1 day. The target's body dissolves into stardust and rises into the sky. The spell effectively extends the time limit on raising the target from the dead, since days spent under the influence of this spell don't count against the time limit of spells such as raise dead. A spell that targets the dead but usually require a body can be cast targeting this constellation instead, provided the spell is cast at night and the caster can see the target's constellation. If the target of this spell is returned to life, this spell ends and the constellation fades.
