Hey, it's ya gal Cthuletta, back at it again with the lengthy posts!
TLDR to Start: I really enjoyed just about every interaction with half-giants. I've had RP where my character is very close to some, others where my character was more-so a confused stranger but overall I found them interesting and the community in Jotunhold in particular to be one of the most inclusive on Arelith. Sure I've had a couple interactions where I wasn't so gung-ho about the other, but we all have different tastes and preferences. By and large, I liked them quite a lot and hope they return as an option so we can see more of them.
On a more in depth note, one thing in particular that I found fun to play out was asking where the half-giant was from and what their family was like. Almost every half-giant had a different tale that lead to how they viewed themselves, either closer to their giant parent, closer to their human parent or just straight up unsure themselves and wanting to learn more about X side. Not to beat the proverbial horse but it is definitely a route you see half-orcs and half-elves go down. Sure, those two have more lore and are more 'accepted' amongst society, though you could argue this is because they're not only more common but also more difficult to identify at a glance compared to a half-giant. Not to mention that setting-wise half-orcs in particular are meant to seen as threatening or frightening but we kinda hand-wave that due to various factors. We're all humans playing a game together after all. Each half-giant was distinct from the other in my experience which makes sense to me. Some of them shared qualities that could reasonably have come from a shared culture on the behalf of one parent, others didn't and it added flavour and variety to a race that could understandably be inwardly conflicted about what they truly are when their physical differences are so obvious to the outside world.
One thing I've never seen was a half-giant posing as a full-blood giant. I've seen one or two comment that they WISH they were, but that's a character's mindset and not what they're trying to portray on their character sheet.
When it comes to the speech that was mentioned, I admit I am horrible at understanding it myself. It was never my forte. Learned a bit, roleplaying with certain people, though I'm far from 'fluent' in Ye Olde English. It lead to some pretty funny situations when my character was very confidently wrong in translations on behalf of them because SHE thought she had it nailed when she very much didn't. I found it curious, interesting and endearing. I'm someone who loves accents and bits of language intermingled to give a character flavour of either mindset or origin so this was something I liked to see even if I myself couldn't always comprehend it. Perhaps that was the point, who knows! Language is very fun and can be used in so many ways to give a certain feeling to a character.
As far as the culture goes, I have a particular view on it. It's by and large a positive one. The lack of half-giant written/canon lore is disappointing, it's even less than gloamings who have... one page dedicated to them? One and a half? This either leaves a lot up to interpretation or a very lost roleplayer trying to figure out 'Okay what now.' when standing in the New Character area. If they've never RPed with other half-giants prior, they're not gonna know what to expect. I think the team writing a bit more on our Wiki with the aid of some half-giant players for the benefit of those interested in playing that race is a wonderful idea!
How I tend to view Jotunhold specifically because of this is that they are a cloister of like-minded individuals, welcoming others of their kind to come and learn of their giant-side history or how to fit into this world that doesn't really have many of them. What happens when a group of people of any kind are grouped together due to their similar nature? A distinct culture forms naturally. You see it all over in Arelith, Bendir and Myon in particular comes to mind. Neither of these places are standard according to the setting lore but have their own unique culture within the rules of the FR setting. Arelith is an island of weirdos! Not just special-race weirdos either, even humans who live on Arelith tend to be a bit odd since we're not playing a farming simulator like the vast majority of Forgotten Realms in lore. Jotunhold might not be a world-wide canon 'standard', but IS there a common standard among a race that is mixed between two worlds like that?
I'm of the personal opinion that Jotunhold is actually quite impressive at creating something from next-to-nothing and having done it so well. If you want to learn more about human lore and gods, just about everyone knows something about them and there are priests a-plenty. On the flip side I really loved learning more about giant culture, lore and gods through IC means rather than a Wiki page, due to some half-giants venerating their giant parent and sharing their love for that culture. It was interesting, generated roleplay and created a story which is what Arelith is for.
Kudos to you, Half-Giants! I hope the option to play them returns.
(Giant-kin options would also be really cool.)
