This is about horses. If you aren’t familiar with horses, you measure their height in ‘hands’ [one hand is equal to 4 inches (101.6 mm)] up to the ‘withers’ which is the point where their back meets their neck.
Surukmak is the Acenta word for horse. The Surukmak were a species of four legged, tall hoofed animals which were used as steeds for a good period of history, until a Arasirikis called Tuthmeligia decided that the Surukmak were too slow, weak and didn’t have enough endurance. So, Tuthmeligia created a new, better horse and named it after themselves, the Tuthmak. These were larger (the lightest Tuthmak were at an equivalent of 18 hands tall (1.8288 metres), the largest working Tuthmak got up to around 24 hands (2.4384 metres) on average. The largest Tuthmuk recorded (easily not the largest ever, as archival and recording is limited in many parts of the world) was about 27 hands (2.7432 metres)), and also heavier, stronger, faster and significantly more endurance.
The fastest gait of a horse, the gallop, can go up to about 48 km/h. A horse at most can gallop for 3km before needing to rest (that’s really quick by the way). A Tuthmak however, can gallop up to 70 km/h, for often tens of kilometres.
This had a major effect when they were introduced by Tuthmeligia, and that was that transport got easier. Large distances are no longer so daunting, since your steeds are just that much stronger.
It also had the effect of wiping out the Surukmak. Consider this scenario, you have to survive in the wild with loads of predators who could very easily kill you (your one weapon is being able to run really fast). Now what happens is a couple Greek Demigods arrive who are better than you in every way… and you’re going to be quite quickly outcompeted and over a long enough period of time wiped out.
Nobody wanted to domesticate Surukmak anymore, since if they went to war and their enemies had Tuthmak they would be (literally) trampled, and Tuthmak were just better workhorses.
So, what happened in short is that one of the Gods learnt (unintentionally) about invasive species and everyone has super horses.
I want to point out that this word T’veran is different to the other landmass names, since its actually not Acenta, but rather derived from the language of a now long lost seafaring kingdom called Knavia, who named the land after their word for ‘Holy’ since they believed they had found some great religious location.
