Hello, this is Zanners the Creator of the mod. but i don't wanna spoil much so here is what ill tell you

the frame of each dimensions portal is sculk blocks
so then for a igniter to each dimension, you will have to...
Put one echo shard in the crafting menu,
then put either of these for Different Phrotons (Ignitors, they are protons with about 20x more energy than light)

Athena/Proxima B = Amethyst shard
Solara/Proxima D = Lava Bucket
Boreas/Ampridite/Proxima C = Blue Ice


Good luck.
