Well I did some research and this is my findings. Tes means Species. It is a mistyping for Teg. Teg is Icelandic for species. The Icelandic thing will come back in a few moments. I word scrambled this post from the source himself. https://www.instagram.com/p/BSoqxHIDQ9V/ Ok now that you have seen it I came up with this sentence Know game of your septs hats. Well here is the thing the septs were a clan of Icelandic people. That's were the Icelandic comes in. This is why I believe the Icelandic meaning is right. The correct meaning of Tes is Species.
