Ran important verbal only messages between Kings and their Generals during the War.
 
During his time carrying messages He learnt of a mythological figure who could freely travers the mist, he appeared to be immune to its poisionous effects. During his downtime or while waiting for an audience with the Lord, Serrich would search each and every library looking for references or clues to the mysterious person's identity.
 
 
After the war Serrich lived well off his trade and skill, moving from town to town creating ballards recounting heroic deeds and events during the war (sometimes enriching those that were dry and boring). His work did not discourage him from seeking information about this mysterious person who he had heard and read about
during his time in the war.
 
Each time Serrich visisited a new town he would religiously scour the library and ledgers looking for new information. Only then once he had read every piece of information did he then talk to every person in the tavern (He quickly learnt the drunker the better).
 
Serrich decided one morning after a long night of singing the (fake) heroic deeds of a nobelmans son that he is not using his potential to its fullest, even though he had written many poems and songs (some of which had won his prestige and notoriety amoung fellow Bards and the rulling class) that they would mean nothing compared to the ballard he would create about the mortal who could feely walk between our world and the mist without suffering pain, torment and death.
 
Serrich began his quest to find this mysterious person by following each and every lead he could find after 5 long years and almost giving up twice as many times he stumbeled upon a traveler that claimed to have seen a person matching that discription recently inquiring about the use of dragon shards.
