Incursean

Incursion are a race of toad-like aliens who apparently love war.

History
The Incursions have been a violent, spacefaring race for millennia. Their original homeworld was divided into many factions in an eons-long civil war. In a millennia ago, an Incursion warrior attempted to reunite his planet with the power of the sword Ascalon, which he stole from Azmuth. The result of misusing the sword's power, however, was the destruction of the Incursion homeworld.

Appearance
Incursions look like anthropomorphic toads. The males can either have slim bodies, warty toad like heads and yellow eyes or in larger forms with an even greater toad like appearance.

The females from the single seen so far look very little like the other gender of their species. Attea the only female Incursion seen so far looks almost completely human except for the not wart ridden green skin, yellow sclera with red pupiled eyes and slightly larger than normal mouth, however Attea is younger than the other Incursions seen so the features are not defined what an adult female Incursions appearance is.

Abilities
Incursions have huge arsenal of weapons. Besides this they have a frog like long  and sticky tongue.

Weakness
They appear to be very sensitive to smells like burning rubber and compost, which causes them to faint (they are also very sensitive to the burning smell of Swampfire).
