There are twelve. Manwë - lord of the airs, he commands the great Eagles, he lives on Taniquetil, he's the King of the Valar. Varda, who put the stars in the sky, lives there with him. Aulë you've met, and his wife Yavanna is the Vala of plants and trees. These are the gardens of Lórien and Estë - he is the Vala of dreams, she of rest and healing - and considered the fairest place in Valinor, and full of spirits.
Then there's Ulmo, lord of the seas, and Mandos, who is trying to restore our dead. Nienna, the Vala of grief and pity, and Vairë who weaves the threads of fate. Oromë, the Hunter, and Tulkas who came down later to help throw Melkor down, and who loves feats of strength. Vána, Spring, and Nessa, the Dancer.
Write write write. Sounds like a pretty conventional pantheon, if gappy and with a focus on things Bella wouldn't assign a whole god to (dancing?) but that's par for the course. Thank you.
They are, um, varied in how helpful they are and not safe to talk to directly for most people, definitely, but they are responsible for most of the healing magic we have so 'no aids' is a bit of an exaggeration.
Yeah. If they were all bad all the time there probably wouldn't be a world left.
Is he more powerful than them individually, or was it just that he didn't care about collateral damage?
It happens sometimes, yeah. By itself, but it's also a known thing with new mothers, usually not so long though.
