Storm Giant Name Generator

Storm giants sit at the top of the ordning, the divine ranking of giantkind in Dungeons & Dragons, and their names carry that weight. Where frost and fire giants borrow from Old Norse, the storm giants of Storm King's Thunder sound Greek: King Hekaton (the Greek word for a hundred), his queen Neri, and their children Serissa, Mirran, Nym and Uthor. Their god Stronmaus is a sky-father in the Zeus mold, and their undersea court of Maelstrom feels closer to Poseidon's palace than to Jotunheim. The names here lean into that register, with -on, -os, -eus and -issa endings and roots drawn from the Greek words for lightning (astrapi), thunder (bronti), storm (thyella), sea (thalassa) and wind.

Because storm giants live for centuries and rule from cloud-capped peaks and trenches alike, many are known by an epithet rather than a family name: Thalmaron Tidecaller, Ouressa of the Nine Winds, Keraunos Boltwielder. A handful here also borrow Old Norse forms for tables that keep all giants in one Jotun tongue, and Greek Titans and Nereids appear for DMs who want a mythic flavor. House and court names round out the list for storm giant dynasties, and any epithet on the longer entries can be lifted and attached to a different given name.
