I'm a big fan of world building, especially when it comes to language. It feels like the Druchii language is more readily available, but I've been curious what the wardancers or bladesingers are saying in their selection war cries in Warhammer 3. I believe Sisters of Avelorn have the same chant.

The two chants I'm referring to begin at 0:25, the bit that sounds like "humble eyeswords".

Edit: so far I only have the parts after, "Autumn comes" and "Loec's plot" (I'm assuming).

Considering the second chant is "autumn comes", perhaps the first word of the first chant is "Hanor", but it also could be "Harvoi"*, and the second word is "Isalt" or "Isst"**:

*This one seems to me to be more in line with their lore.

**They serve Loec, which is why I lean towards this rune, but as you have noted Sisters of Avelorn also chant it - though I don't think there is necessarily a conflict because it offers a couple of meanings. It is one of the two, of that I'm almost sure.
