Appologies if you are already aware of the following First Age - but I thought this may be of interest.

The usual approach to running a BoL Conan game is to grab a copy of the Mongoose book Road of Kings and slap BoL on top.

 Jeff Mejia’s ‘Dicey Tales 2’ pdf includes a bestiary for pulp era adventures, which is useful for Hyborian games as it includes horses, wolves and other mundane creatures, (although stating up your own is hardly arduous).

The Strange Stones site hosts some BoL scenarios by G-Man. There are 3 Hyborian scenarios and also 3 Dark Fantasy/Lovecraftian ones that could be fitted into Hyboria with little work. You can find them here:

An American gamer who posted as daddystabz on the old Lords of Lemuria site did a lot of work on a Conan BoL game – a post about it can be found here:

Note that Lords of Lemuria died by spambot, so although there is good stuff there, it’s time consuming to find it now.

Note that all of the above are Legendary Edition material.
