I thought perhaps in the future more runes could be designed with Darkmarsh in their name without being a Boghopper. If that happens I would suggest amending Warsong to include units with Darkmarsh in their name. Perhaps a couple Mirefolk listened to Lemsu, ofc I'm already thinking of a Darkmarsh Troll. Darkmarsh G'hern? Tortun? Besides the Darkmarsh flavor texts, is there any more lore on Lemsu?
