This spell is a short tune played on a magic wind instrument (traditionally a whistle) that calls 1d3 byakhee through the void from their native star. Due to the spell’s magic, the byakhee hear your song with their time-distorting hune organ long before you begin casting.

Thus, although they have been flying under their own power for potentially a long time, they arrive immediately upon the conclusion of the casting at a location of the GM’s choice within range. Roll initiative for the byakhee, which have their own turns. They are not under your control. The byakhee are hungry and liable to attack you but are content to be still and listen to singing or a tune played on magical wind instruments (whether magic items or mundane items under spells), including as part of the spell bind byahkee.
