[ If like, death is the only other option gaining powers to manipulate time and space instead is pretty sweet, actually. ]

Each individual Siren had her own unique set of powers, some similar to your ability in that another plan of existence was accessed and moved through, another used that same plane to halt perceived enemies for a period of time, trapping them between dimensions. Another....she could manipulate world around her, though her powers were siphoned for more specific purposes, as far as I know.
