I am certainly planning for the Tytoss to be a particularly neutral and mysterious race, with very few other races knowing much about their society. Though I'm avoiding the 'wise owl' trope, I'm aiming for the Tytoss to be particularly aloof and distant from the other races, referring to them often as 'Groundlings' or 'Climbers', and interacting with them only when it suits them.
This works.
They might get a reputation for wisdom by being mysterious whether they deserve it or not.
Whether or not the groundlings know what the owl people want,
you should know what you want.
In my world, I usually focus on small scale conflicts not epic world changing events, but I do give some thought to epic world changing events.
Flight, even limited flight is a huge advantage. A small number of owl men should be able to obliterate a group of humans with superior numbers between their flight and (presumably) night vision and stealth.
Maybe I am cynical or a closet sociopath, but whenever I create a fantasy race, I ask myself the question. "What would happen if this fantasy race faced an enemy that has genocidal ambitions?" In fact, any race that survived the Second Unmaking
did face an enemy with genocidal ambitions, but I'm still mostly thinking of human or humanlike enemies, not Lovecraftian demons.
Scarterran gnomes are good at talking, but if talking fails, they are in serious trouble. Their low strength is a huge liability, even with their stealth bonuses, they would not fare well in a total war scenario against humans.
What has kept the gnomes alive so long. Well one, they are good diplomats, but just in case they have the Order of Delas. It is well known that princes that routinely murder gnomes
en masse have a strong tendency to drink from poisoned cups or have their throats slit in their sleep.
The Kalazotz are one of the younger races in my world. They never faced a wide scale threat against their whole race. As of yet, they do not have an effective means to defend themselves from
ordinary humans using total war tactics. That's why most of them stay in very remote areas or have allied themselves to mighty dwarf warriors.
Humans are slower to develop from child to adult than any known animal. Owls have a fairly long maturation period compared to other birds (as is the case with many raptors).
The Tytoss probably stash their babies and juveniles in tall trees.
A genocidal opponent would try to chop down their trees or set the forest on the fire.
What can the Tytoss do against this strategy?
That's essentially what killed the Grey Forest Kalazotz in my world. Their treetop homes were cut down and they were harried so they could not rest. Remember that is how prehistoric humans hunted. Human aren't faster than other animals but they are
relentless trackers and have great stamina on long runs.
