Back in the days when we were just nub who was derping around we found a peculiar egg in Balnamoon cave.A cave habitated by slugs,trolls and yetisaurus,we find the egg among others in the yetisaurus section of the place.The shell of it looks crystal,is very well known that they are birds who lay eggs in the nest of other birds.So lets assume that the egg is not from a yetisaurus but from a troll(dont ask me how humanoid creature can lay eggs).Later on we start investigating the Crystal caves ,we find there a hatched crystal egg and in the end of the day we fight and defeat a troll who is a lot bigger that us.It cant be the same egg,is different colour and the "baby" doesnt look like any of my brethrens back in our home cave.Ok lets now travel back in time,we bring the egg to a scholar outside of the cave who studies trolls.She doesnt know what the egg is and says to bring it to Professor Heinrich,who funnily enough doesnt know what it is also.Few lvs before that we fight and kill infernal scouts just outside Nidaros ,where is the home of the kind proffesor.If infernal scouts infiltrated the Eldevin kingdom once,they can do it again . They are 2 possibilities:
1)The egg was stollen and the proffesor decided to not make a fuss about it
2)Heinrich gave the egg to the infernals,he is a traitor and supplies with info his dark masters.Surely a proffesor like him have some juicy info.Of course there is always the posibility the infernals treatens his family if he has one,something we arent familiar with(the family thing) .
Personaly i will go with the first theory but surely he would discover the powerfull magics in the egg .... And make fuss about it,right?Maybe the fuss didnt reach the ears of our char.Now lets continue with the story ,the egg is in the hands of the Infernal emperor.He discoveres at some point in time that someone else than him wants to destroy his enemy,the enemy of my enemy is my friend.Now lets go back to where i say it cant be the same egg because of the difference.Well what if is the same egg,what if someone experimented with the trolls in that cave.Mage Vilkarax,it all makes sense isnt it?Rumble would have been mighty weapon during his war against Eldevin and if he failed at least he would have weakened our beloved kingdom.Weakened enough to ensure Tristan victory.You may ask why the infernal empire took the egg,why couldnt the powerfull wizzard do so?Well first of all Mage Vilkarax is man of magic,not some petty thief.Why to dirty his hands when someone else can do it?Surely Vilkarax and Tristan are alies,with one conmon goal.The destruction of Eldevin.What if the future we see in the begining is alternative one ,one in which we dont defeat Vilkarax ?Or maybe we never killed him,maybe he is still somewhere there in the world?
Fire,i like fire.
