I'm struggling to find a motivation for a Lizardfolk character to join an adventuring party or to go out and discover the world.
Reading the description from Volo's Guide to Monsters, I'm getting that they mostly stay in one place with their tribe and are focused on survival.
Lizardfolk focus on survival above all, without sentiment.
They are also not driven by emotion, so desire, curiosity or revenge are also off the table.
Lacking any internal emotional reactions, Lizardfolk behave in a distant manner. They don’t mourn fallen comrades or rage against their enemies. They simply observe and react as a situation warrants.
Lizardfolk lack meaningful emotional ties to the past. They assess situations based on their current and future utility and importance.
Volo's Guide states:
Some Lizardfolk make an effort to understand and, in their own manner, befriend people of other races,
However, why would you adventure with others if you can survive on your own?
Is there something I'm not getting or is it really hard to make a Lizardfolk a good party member without ignoring all the facts about the race?
TLDR: What would motivate a Lizardfolk to join an adventuring party and to stay with them?
Edit/Update for more clarification: I'm looking for examples from the rulesbooks or adventures (preferably citations) of Lizardfolk who joined adventuring parties and about their motives.
I myself couldn't find anything more with the material I have and was curious why any Lizardfolk would abandon their tirbe/home to expore the world with other races.
