While love describes the bond between two people, the realm of Sindri lies more in the emotional turmoil of want. Whether it is lust, greed, or longing, Sindri encourages his followers to press for their hearts' desires beyond what is healthy or normal. The god and his worshippers see this as a drive to achieve or obtain what they do not have. This appeals to a certain type of person, but to others, it's wanting something for the sake of wanting and not need. And in that, most see Sindri's encouragement as an act of evil. Sindri is said to have a hidden grove somewhere in the world where one can sleep and dream of that which they desire most.
During the Constellation War, Sindri often played with the minds of the gods of the multiverse, convincing them they wanted something self-destructive. He convinced Mystra, goddess of magic in the multiverse, that she wished for mortality, causing her to give up her divinity only for Sindri to then strike her down. Sindri himself met his end at the hands of Leira, the only god who could match his mind games.
