Gabag had been sitting in the tavern quietly, all the way in the corner, soaking up all the information he could. Since he was a mercenary assassin from a foreign land, recently hired to kill people, it helps to know about where you are. When he saw five armed soldiers arrive in the tavern, he thought it was the king's men coming to raid the place, like he heard happened to other towns and such. Now seeing a panicked person storm in, and immediately talk to the tavern keeper, thats when he was interested.
When he looked on, they recognized each other. Armed men, courier arriving very quickly afterwards, it was all too obvious. His target was somewhere in the tavern. The tavern keeper was probably playing messenger boy to the elusive General Tar-Ryn, however there were still too many armed soldiers in a confined spot.
Standing up from his silent watch, he slid a sack of gold behind the bar as payment for his meal and drink, then made to leave the tavern.
"Excuse me" he said politely as he nudged his way past the soldiers and the patrons.
Outside, he concealed himself behind the tavern, and waited for his... informants.... to leave.
