Exactly. It's basically as simple as whatever feelings say, a Mind Flayer initially made you feel, you expand upon that. The cosmic feeling of existential terror a being like a Worldflayer Cogent would evoke. The horror of staring into the hundred eyes of the dreaded spawn of the stars Cthulhu. Etc.
Shatter the planes and see what's there but don't just ignore or dismiss the body of knowledge you can acquire just because there's something higher.
At a certain point, if you use 10 dimensions theory as a baseline, it's impossible to actually conceive of higher concepts intellectually.
Since this is a game format, however, things have stat blocks, but stats with no mind behind it, no point of reference for the player's to actually interact with, becomes simply statistical masturbation.
So, Thychen could have been highlord lvl ∞, but the point is for players to eventually, possibly, either become the Supreme Being, merge with it, or something along the lines. I already had Gamma, who, is in essence just a being from your Cosmos Apep, and the Guardians who remain statless but are even level with Thychen, but if every interaction was just some naughty word where the player's had no real power, they'd feel like plankton helplessly floating around on an ocean they can do nothing about.
To hell with that. D&D is supposed to be about changing the future or changing the world in your campaign and being inspired. Not just a sheer intellectual exercise.
I just think the majority of your work is unusable sadly, though I still really like Bythos and implemented it in my campaign, but you basically used the framework of everyone else's work to create it then claimed how easy and lame it is, but that's inherently flawed and frankly, pretty dumb.
Admittedly, for my Riem and Actoshen posts I borrowed mathematical underpinnings, but I at least honored the original writer of the first statted Time Lord, Avinion. Whom without we never would have even had a chance to explore this frame of mind.
I'm just saying. We like your work. I like your work. But you crap on everyone and everything. That's not cool and you look ignorant because you don't have an actual experiential pov.
You've never played a full on IH campaign from lvl 1- Timelord. Or even ar all probably. Never seen how it all works out ultimately. But you talk talk talk like you're the cock of the walk. I'm just saying. It doesn't look good and doesn't always work out. It's smug, and stupid. Blind. Sorry not sorry.
Hopefully wherever you end up, I hope it works out for you. Thanks for the superbeings.
