Bored noblewomanHalf-orc child acquired through the slave trade, but was quickly dumped on the streets when it became apparent it was sickly and proved to be no good for manual labour. The local thieves guild trained it up as one of their street urchins, their eyes and ears, however the creature was always plagued by a mysterious illness, being malnourished and living on the streets certainly did not help matters. Then one eventful day the Horde knocked on the town walls...
Taking pity on the bastard muggle that survived the onslaught, the local shaman/warlock of the tribe managed to shake off the child's illness/curse and so blossomed the half-orc barbarian, the secret weapon of the Horde.
Whenever the Horde desired to pillage a settlement, they would send in the half-orc who spoke the common tongue fairly well and had a knack for deceit having picked up the skill during his years on the street. Pretending to be trader/travelling labourer, the half-orc would scope out the village/town's defenses and report back to the Horde.
