Me about everything

Im on top of the world

But i am all alone.

So i wonder

If a life with you

Would have been worth

Losing it all?

here's a question i've had before: how does monster aging work in mtau?

for example, horror is 58 yrs old if i remember correctly, does that make him relatively old or is their lifespan usually longer than humans'? (i imagine average lifespans also differ between boss monsters and the rest)

TAU horror is 54, but close!

i'm pretty sure i've talked about monster aging before but i can't remember where the post is — TLDR; a monster's llfespan depends on how much mana it generates, which typically correlates (at least roughly) to its size. it also isn't a straight graph of "more magic = more life", because mana slowly wears down a monster's leylines similarly to how oxygen slowly "burns" our cells; there's a sweet spot in the middle where you can have enough mana to live a long time but not enough to burn your body and SOUL alive from the inside.

(and you're correct: most boss monsters normally sit somewhere around this sweet spot, hence their longevity irrespective of size. :>)

how quickly an overabundance of mana can kill you also depends on the type of body you have, which is why it's important to consider the "race" of monster. ghosts and skeletons, for example, don't have a lot of physical matter even by monster standards, which means that even though their leylines play a more important role in their bodies they're also more resistant to those leylines getting worn down. this corresponds to the idea of "undead" monsters living a very long time.

(...that said, the point where a monster reaches "maturity" also depends on the type of monster. generally speaking, more humanoid monsters will reach maturity rouuuughly the same time as a human — maybe a bit older or younger. this is, again, more to do with the size of the monster than the shape; if a monster was humanoid but also the size of a cup they'd probably reach maturity in just a few weeks. but most humanoid monsters in undertale are also humanoid in size, so... let's take that as a hesitant norm across most universes.)

anyway, with that out of the way, and given the context that all of the pantheon members (obviously save abaddon and nightmare) are boss monsters (lots of mana) AND skeletons (not a lot of physical matter to burn), this means that their lifespans are naturally going to be very, very long. like, at least a couple thousand years a piece. (which seems overbalanced until you remember that skeletons are typically pretty rare in their home universes; seeing more than 3-5 in one spot would normally be very strange, multiversal shenanigans aside.) HORROR, however, comes from an anomalous universe where monsters are made of flesh and blood instead of dust, which means that he does have a lot of matter — and that unfortunately means that he is going to have one of the shortest lifespans on the team besides dust himself, who already suffers heavy leyline damage from the condition he has that causes his body to overproduce mana.

all that to say: horror is still pretty young by skeleton standards, but he'll probably only live a couple hundred years (if he's lucky) as opposed to the more typical few thousand. that's not to say that he's a child, either, of course — all of the skeletons are well past the age of maturity, and in that way "their" 54 isn't really different from 54 in a human — but he's not quite on his deathbed yet, so no need to worry.

so i'd say horror (specifically) is like... late 20's, in human years?
