Keepers of Thunder
Siege warfare and combat engineering are the specialties of the Kech Hashraac. The Dhakaani don’t employ siege staffs or evokers, and the Hashraac has spent generations developing new weapons to dominate the battlefield. If the DM wishes to add the conventional firearms and cannons presented in the Dungeon Master’s Guide to a campaign, the Kech Hashraac could have developed these weapons during their long isolation. Alternatively, the Hashraac could specialize in the enhanced artillery described in chapter 1, alchemical explosives, or an entirely new form of weapon.
The Kech Hashraac have yet to reveal their presence to the world at large. While few in number, the force they command could be vital in any conflict that lies ahead. Will they support another kech claiming the imperial throne, or will they pursue it themselves? The warlord Duul Hashraac leads the clan; he is noteworthy both for being a daashor as opposed to a common warrior, and for using his clan name instead of “Dhakaan” as his sobriquet. Duul is proud of what his people have achieved; whether he seeks the throne or serves as kingmaker, he believes the Kech Hashraac hold the keys to Dhakaani victory.
The Kech Hashraac are a logical choice for a Dhakaani Artillerist artificer; the artificer’s magic can be tied to the tools the DM chooses to provide to these Keepers. A Hashraac player character could be dispatched to study the battle magic of the Five Nations, to seek out rare components needed for new weapons, or to investigate the Mournland and the theory that the Mourning was caused by battle magic. Alternatively, a Hashraac artificer could have left the clan to pursue their own unorthodox weapons research, hoping to return in triumph once they have perfected their techniques.
