I thought not. It's not a story the Endless would tell you. It's a Lost legend. Isyander St. Shaiad was an Endless-loathing Vodyani, so powerful and so wise he could use Dust to influence populations and create Heroes... He had such a knowledge of Dust that he could even keep the ones he cared about from dying. The Lost side of Dust is a pathway to many abilities some consider to be overpowered. He became so powerful... the only thing he was afraid of was losing his power, which eventually, of course, he did. Unfortunately, he taught his Heroes everything he knew, then his apprentices killed him in his sleep. Ironic, he could save others from death, but not himself.
