Hi, You were asking where to get 'Dark side of the Sword Coast'. well ,Guess what?, its here,
www.dsotsc.com ,-strange huh?
You need 'TotSC'installed and patched(i never used the patch with no problems)before installing DSotSC.
This Splendid expansion includes: 5 new NPCs(Paladin,Bard,Cleric,mage,and?),Five major quests with probably as many new areas.Theres lots of undead to fight,and a forest dragon.
The new quests start when you exit cloakwood mines,but you can pick up one of the NPCs when you exit Nashkel mines earlier on.
