He may be invisible, he was for me. He is next to a lazurite next to the stairs. You barely can see him.
He's actually laying down near the battlements above. He's very easy to miss. I looped the whole keep area and kept walking right by him.
Yes, what tekmage said ... unless you kited him someplace else during the fight, he's most likely laying down atop the battlements (wounded, with a word balloon, awaiting your decision on kill or capture & judge), just below the outcrop with the two big stone statues. Easy to miss, as his gear is light colored and sorta blends in with the stonework, esp on a small screen.
I played on PS4, and couldnt find him right away either.
Went back to check..again...hes not there...theres a Venatori brute, roamer and 2 archers..up on the battlements. thats it. Im playin on PC.
Best of luck on the PC version ... what little I've read to date seems to indicate it's more buggy than the console version, and performance issues seem commonplace.
Not to get too off topic, but other than a missing npc, i havent had really any trouble playing PC. First week a couple desktop crashes, but after the patch all good...but Servis...grrrrr
Sometimes NPCs fail to spawn, or spawn on the opposite side of the map. I've found, though, if you quick save right in front of where the person is supposed to be, then reload, they'll usually spawn on reload.
@ladylily1 is correct. Servis sometimes fails to spawn, or spawns "invisibly" at his spot on (in?) the wall at the top of the stairs in the Echoback Fort.
AFAIK, after over two-dozen playthroughs on PC, re-loading a save from right before or after the battle is the only way to overcome this bug. (And no, it will never get fixed by the devs. All support work on DAI ceased with Patch 11 after the last DLC was released in 2015.)
