like some pagan metal thats really fast, but still harmonic, with insane guitars and drums and an awesome singer? preferably refering to actual pagan Dieties, not from the viewpoint of christianity, not of evil alignment, but i mean if theres some i guess thats okay?

tryna do some nature magic, cast a decent fairly permanent impermanent circle to stop some ruffians desecrating the wood for some reason

mugwort!

Tuatha de Dannan, Icarus Witch, Huntress, Moonstruck, Gypsy, Incubus Sucubus (their track Witches 2000 is amazing!) and while not strictly pagan, Within Temptation( tracks like Ice queen, Aquarius, Jillian) Nightwish( Elvenpath is a good song) and Lacuna Coil ( My spirit is a great one) are also good bands.
