once per day, This feat allows a caster to instantly transport themselves and up to eight willing creatures of your choice that you can see within range, or a single object that you can see within range, to an Echo-Plane in Limbo, where time does not exist. If you target an object, it must be able to fit entirely inside a 10-foot cube, and it can't be held or carried by an unwilling creature. The destination you choose must be known to you, and it must be on the same plane of existence as you. This Demi-plane shifts between the planes of existence, and is subject to various changes at any given time. while no time passes on the material plane players must travel the echo-plane to their destination. this echo plane takes on various attributes from the surrounding planes, making Warp travel to a specific destination difficult without a clear destination in mind or a Beacon on the material plane calling to the player. Teleportation circles act as beacons, if the caster knows the sigil by heart. the Spire acts as a permanent Beacon. 

should the caster or his allies be rendered unconscious during the Warp they are expunged from the echo-plane somewhere between their destination and their original position, as determined by the DM.

While traveling to a place the caster remembers, other memories can become twisted by the nearby plane of Limbo, manifesting in the echo-plane.

when traveling to a place the caster has only heard of, the stories and rumors surrounding this place manifest in the echo-plane.

traveling to a place the caster has been lied to, results in the lies becoming truth while on the echo-plane.
