Forgotten Realms: Erevis Cale Series by Paul S. Kemp

Erevis Cale - simple butler or much, much more?<The shadows grow long on the mean streets of Selgaunt... and the sun sets on one man's service to Sembia's merchant lords.The day's end finds Erevis Cale serving a new master, one who is beyond the petty accumulation of wealth.After all, what is gold to one who trades in souls?

The shadows recede from a lost temple in a forgotten wilderness.The sun rises on a new calling for a man as loyal as he is mysterious.The day's beginning finds Erevis Cale holding in his steady hands more power than he dared hope for - and more responsibility than he ever imagined.For now, he will have to put his trust in a god served by thieves and born of chaos.

The shadows deepen in every corner of the Realms.The sun no longer shines on a man who has embraced the darkness within him.The day's opposite finds Erevis Cale so far along the path away from his own humanity, he may never again walk as a man.In the end, to be Chosen by a god like Mask is more curse than blessing...
