From their D&D stats, I was going to gauge relative power levels with the other Immortals. But their absence makes things tricky.
Now I have a different approach. If I can establish them as being part of the Mystaran Universe, with the rest of the Immortals as a huge group of PCs, then all the stats that talk about ranks being First + 1 or First + 2 (in other words a rank or two above the highest ranking PC in that stat), then I just have to deal with the stats of the Immortals as a batch.
Consequence: the Olympians are top dog in terms of power, and thankfully missing (or pursuing other projects in the multiverse).
Fortunately there is much out there that I can already use to support such a theory:
- this list of Mystaran Immortals identifies (among many things) existing Immortals who are worshipped as the Olympian deities in the Milenian culture (found in the Hollow World)
- here's a theory about the IM2 module and the false Olympians found there, and introduces the Mandala of Myth artifact
- this article expands on that false Olympian theory, and further rationalizes the events in IM2 in terms of Olympian gods from the Plane of Myth
- this Mystaran Cosmology post establishes where the Plane of Myth (Laterre) might fit into the overall cosmology and the other playgrounds of the Olympians
- this post shares a bit more about Laterre, and other cornerstones of the Mystaran Universe that came from that plane -- like a couple of families in Glantri, and one of the Immortals (Rad)!
