Summoners Rift braziers

Hi, i need your ideas.

Today i wrote a support ticket (thx Riot KramSyhr for the quick response) i want to share here:

My son (2) likes to watch me play League of Legends, and every so often we take a tour of Summoners Rift. He especially likes to watch the dragon and the braziers. So here is the question i ask on his behalf: Who lit the braziers on SR?

Answer was as follows:

_Hi there, This is Kramsyhr, and I will be your support specialist for today. That is a good question, mate. The Summoner's rift is shrouded in mystery and there is no written history on who lit the braziers. There is only a few information about SR and you can read about this on the link below. _

So I'd like to ask you for your ideas about who lit the braziers on SR.

• Are they always burning or are they lit before every match?
