I would like to add to this, did Tinto really initiate the war or battles with Grassland? I remember Lucia in S2 having a huge quarrel with Teresa the Mayor of Greenhill. Teresas' father poisoned Lucia's father at a peace agreement landing her the position of Chief of Karaya. I know Tinto and Grassland had many skirmishes due to their borders and possibly Tinto wanting to expand but as for any war I do believe that Greenhill started the war with Grassland.
