Yet Kavenagh, for the large part, seems unfazed.
Theres a calmness about her throughout our interview.
It could be tiredness from the night before, but it strikes me as more than that.
Shes taking the experience in her stride, whilst still making sure not to take it for granted.
A remarkable moment for anyone, especially a young actor in the very early stages of their career.
But I couldnt tell anyone, so I had the most, like, internal celebration, remembers Kavenagh.
I might have told my mum [brief details], but the rest was very much on lockdown.
Its exciting when it is finally released.
In this case, me.
A character created specially for the series, teenager Nori holds an almighty presence among her fellow Harfoots.
Shes mischievous and inquisitive, with an endearing penchant for getting herself into trouble.
At the heart of Noris story lies The Stranger, portrayed by Daniel Weyman.
The giant-like figure falls to earth from a burning ball of fire that has torn through the sky.
Fan theories have pegged him aseveryone from Sauron to Gandalf.
I ask Kavenagh what she can tell me about his identity.
I genuinely dont know!
You think a character is one thing, and then they surprise you.
There were very technical scale explanations.
Daniel and myself couldnt act directly opposite each other, so it was a very new experience.
As a result, some of the scenes featuring The Stranger involve clever manipulations.
Maths is beyond me, so I couldnt tell you the technicalities, Kavenagh laughs.
Thats not my hand.
Its a visually stunning series, giving life to magical worlds and beings.
And theres been some real-life lessons at the core of this journey for Kavenagh.
Their openness allows for better communication and greater change within the community.
I really admire that about them.
The actor, along with many of her co-stars, is now firmly under the spotlight.
I want to be careful that Im present in my real life.
Ive known them for years.
We all support each other in whatever we do, the actor shares.
Away from the series, Kavenagh is honing an off-camera passion of hers.
Its for an initiative in Victoria, which is very exciting.
And with that, our time together is up.
I look down to see a selection of biscuits.
Not a snail in sight.
With a sigh of relief, I make my goodbyes and head for the door.
