It's quite nice to see another goblin character coming about! There's only a few things with his backstory and the timeline of events that require some clarification.
It is mentioned that Skrimp grew around the war, which leads me to ask if you are referring to the Pact War. Should Skrimp be only 17, he would have actually just missed the end of the war between the Pact and the Alliance by a year. At this period the conflict would have since met a sort of conclusion with the Obelisk destroyed. Most of Skrimp's experience with this time would have simply been the aftermath and the prejudice that remained among the races, or perhaps a few remnant demons that took refuge in the mesa domain.
Besides this comes the matter of Skrimp's experience with the plague. The main question is: Had Skrimp ever moved on from the mesas to live within Barkamsted or Falkvard? Did his family or kinsmen ever come to the decision that they could thrive among the western cultures? It is only mentioned in the last portion of the biography that he decided to leave his home, but does this mean the desert or merely his family? Had he or those he was related to chose in favor of remaining separate from the Alliance races, it is unlikely he would have left the deserts during this time to see the full frontal force of the outbreak that spread through the major cities, most namely Barkamsted. If he did at whatever point move to the cities, I would like to see how that transition came about. Describing how he found his place within Barkamsted/Falkvard, what sort of people he met, or who he reported to as a scout against the masses of undead would all be beneficial to bringing out more of Skrimp's backstory.
Alternatively you could scrap out the portion with the plague if Skrimp would have still lived in the mesas at that time. I see you make mention of 'the fighting halting a year ago' though it's a bit vague which conflict this pertains to. If you are referring to the internal campaign between the tribes of orcs, it would be best to clarify that. If you go with this option then I would only ask what sort of role did he play during all of it? What impact did it make to him and his ideals? More information in summary can be found in the site's general lore near its very end, specifically here--
Year 88 of The New Era
It would not be long before further war plagued the people of Saphriel. With the unexpected death of Chieftain Oomjor, a leader among the Orcs desiring further ties with western, Alliance races, a power struggle erupted that grew into an all-out war between those that sought ever-closer union, and those who wished for the mesas to remain independent of western interference, and then those who sought to begin the Pact War anew. The latter was a particular threat, aided as they were by the distant remaining Cult in undead men, monsters, and resources. While much fighting happened on the part of the Orcs, it fell to the Knights Order to aid the remnants of Oomjor's tribe, battered by the war and a new brutal leader who ruled for power alone.
After much fighting, they were victorious; the Cult once more pushed back, ties between some Orcish tribes and the Kingdom have, at least in theory, grown closer since. Yet even after the war, those Orcs that embrace change from the West are ultimately a minority; many Orcs remain that would prefer separation from Western ways, if not another war. Back in the west, the prejudices against the Pact races remain in the cities, the genocide of the Pact War understandably far from forgotten There remain some in both the East and the West who strive for mutual understanding to advance the Mesa and the Kingdom. Whether their efforts succeed, only time shall tell.
For reference, it is also year 90 of the New Era. Just bump this thread once you've made the edits! Feel free to message me if you have any other questions as well. ^^
