As cautiously as possible, Ælfric stalked into the archmage's sanctum sanctorum. His first aim was to safely reach the large and perhaps too obvious book, ascertain if it actually was the grimoire, and secure it without setting off any traps or alarms whether arcane or ordinary. If he got the book without being vapourized or alerting more golems, Ælfric would look for somewhere to put the surveillance gem where it would be discrete and beneath at least immediate notice. After that, he would get the Nine Hells out of there!
