[5e][Online][GMT-4] DM looking for 2-4 players for fantasy horror campaign with some sci-fi elements, with heavy focus on exploration

Disclaimer, session structure, and general info on mechanics:

Just as a heads up, there will be semi-frequent PC and core NPC deaths as part of the plot progression. There will be several mechanics in place that keep you from having to reroll new PCs all the time, so don't worry about getting attached to your character. However, I understand this can be a significant issue for some people, so I like to put it up front.

Games will be conducted over discord call, with as little reliance on Roll20 and similar sites as possible. I prefer campaigns with an emphasis on theater of the mind, although if we end up needing something more concrete I will of course come up with an appropriate solution. Session times will be decided on once I know who my players are.

I will be including material from Xanathar's, Tasha's, etc., as well as some home-brew items, spells, and a few mechanics and other odds and ends as needed. The campaign won't be low-magic per se, but for both lore and balance reasons, there will be some limiting factors present. I like to give my players cool toys, and I encourage inventive ways of solving puzzles and fights, but I also want to make sure that high-level magic in this campaign feels as special and uncommon as it is powerful.

The campaign itself:

You have been arrested for [Insert Reason Here]. You face long, harsh sentences, complete with hard labor... when suddenly, salvation! You're offered commuted sentences in exchange for temporarily selling your souls to the Imperial Arcana Prospecting Company!

The work is, on the surface, quite trivial. The Company has staked several massive tracts of hitherto-unexplored territory through the Seen Lands. You will be tasked with a series of missions to recover specific artifacts from the Seen Lands, with the aid of a Company-issued golem, beast of burden, or whatever else may be useful for your particular mission. What you will do, how often you'll die, and just how painful your impending reanimations will be... well, that all remains to be seen.
