The Black Star

A spell crafted by Simon, The Dark Star. Capturing the unrelenting hunger of Hadar it's existence to inspire and influence his arcane equation and peering closer than most mortals would dare.

You and up to eight creatures who are within the 60-foot-radius are effected by the spell. As you cast this spell you can specify a target destination in general terms, such as the City of Brass on the Elemental Plane of Fire or the palace of Dispater on the second level of the Nine Hells, and you appear in or near that destination. If you are trying to reach the City of Brass, for example, you might arrive in its Street of Steel, before its Gate of Ashes, or looking at the city from across the Sea of Fire, at the GM's discretion. 

Alternatively, if you know the sigil sequence of a teleportation circle, this spell can take you to that circle. 

All creatures other than the caster must make a Charisma saving throw or take 4d10 force damage and 4d10 necrotic damage and if the targets are not native to the plane they are ejected into the astral sea facing the distant all hungering red star. If a target succeeds their save they take half damage and are not transposed if they would.
