Weird mod from the past

I (Sort of) remember a mod from the past that I would like to find if possible. Given that my memories are shady, I will provide with all I remember, hoping that I'm not confused with content from other mods.

The mod I'm talking about had you buy a vial\sphere\an item from Ribald so you could summon a npc that would have joined your party.

I don't remember anything else. Sorry.
