Okay, can you fill in the missing parts for those not in the know? Why would a dragon (drake) come with the first orc that approached him?
So I don't remember my specific thought process at the time, however, back in Lordaeron Turn 5, you had the following vote:
You sense a:
Choose 1:
[ ] Wandering child, lost, in pain, confused and afraid
[ ] Vigilant soldier, ready to shield their liege
[ ] Loyal servitor, diligent and true
[ ] Vengeful sufferer, waiting for their time to strike
These were at the time basically plot hooks, like several others I've been scattering about as the quest has gone on. There's a lot of stuff going on that Grok may never (be directed by players to) encounter, and that's ok, but it's relatively easy for me to play around with the hooks in any case. Here for example I think each of the options was a dragon, which partly would have been intended to lead you onto other stuff. For example, the 'Vengeful Sufferer' was
Torth, an enslaved Black Dragon in the Dragonmaw camp. He might have escaped and subsequently, you'd have engaged with Dragonmaw stuff. In this instance though you chose the Wandering Child, which was a child of Searinox. I don't recall what the servitor or soldier were, but they would have been other dragons. I just remembered Torth's name etc.
Part of why there's a dragon now is because dragons are cool, and it's cool to have dragons. They're an important thing in the setting, and the Blacks especially are connected to multiple parts of the Horde, notably the Dark Horde, and Grok would have encountered them eventually anyway. So that explains why there's a dragon in the first place.
Now, as for why would it go with Grok, well, firstly because he's a persuasive guy, the dragon feels safe with him or something. Secondly or more importantly though, it's sensing his big Earth and Fire connections. The evolution chain goes from Earth elementals, then the Stone Dragons, then Protodrakes (presumably suffering the curse of flesh), then the Aspects and their children, and of them the Blacks are obviously still very 'earthy'. Here the drake is sensing Grok's shamanic connections, his mastery over Myzrael and the elementium on his bracer, as well as the essence of Grond in his blade. Here Kalaran was trying to talk to it in Draconic, but it's a feral child so doesn't understand him. Maybe if Kalaran transformed he could have got it to listen to him and follow him back to Onyxia or something to take care of it, but he didn't want to transform for various reasons. The Drake could recognise that Kalaran was dragony, but didn't see him as a dragon because he's in disguise etc.
Some of the options look like they're time limited too.
Indeed, however, for example:
Main difference is the trip to Stormwind. Several fluff nudges have been given, best to follow up on them.
Some are indeed time limited, but to a greater and lesser extent. For example, Bishop Karlus and Grok believe that unless Grok tries to get a favour from the Stormwind clergy, Lord Gregor will accept the pressure from the Lordaeron clergy and a Lordaeron priest (so part of Dathrohan's faction) will be elected. That's not necessarily going to happen tomorrow, Lord Gregor would be involved in negotiations for a while for concessions, material support, security guarantees etc, but it's going to happen.
Comparably, last turn I rolled for situations you weren't a part of. For example, I rolled for Gilneas and what was going on there. If you didn't send them help and they rolled badly, that might just lead to the destruction of the kingdom, so that would be an action which is determined by rolls.
Comparably, you've then got actions 'on a timer'. Those are things which are going to happen at a certain time or because if certain actions, which you would have to prevent for a particular reason.
