Goblins

Bugbears and Hobgoblins are established races. They are not altered in the slighted bar the lack of their pantheon - everything else about them is the same as in the sourcebooks for 5e. Goblins are mostly the same too, there is a tiny alteration to their mannerisms and that is about it.

The Titular Treasurehoarders:
Goblins love one thing in life above their precious 'shinies'. It is not the admiration of a screaming crowd, it is not the skill required to cut a gods head clean off, it isn't even overwhelming arcane power. It is simply a name of themselves.

Goblins love Titles above all things, more than gold, and more than power. A Goblin knows that material wealth is not unique, any adventurer in Nevandaar could have a net-worth of several million gold - but there can only be one: Sneev 'Kicker of Trolls'.

Goblin adventurers will often carry around small scroll-cases with them. Housing all the official titles they earned from adventures long since passed. They look after these scrolls as if their lives depended on it. To a Goblin, whilst being offered a monetary reward is nice; they will oftentimes ask for a title to go alongside it.

A typical Goblin adventurer may introduce himself as:

Katch: 'Thief of Darkarth' - 'Diplomat of the Highking' - 'Slayer of Dragons' - 'Savoir of the Grung' etc. etc. etc.
