As with the past few votes that had similar open-ended Q&A sessions, I encourage everyone to include most of the default options. The whole point of seeking out these Guild enthusiasts was to to gather information to better inform our Guild choice, so the more information they can give us, the better.
(Honestly, I think a lower vote threshold subject to QM veto might be better for info-gathering sessions like this. If there are enough options, the vote will often be split enough that most questions have trouble passing the 50% threshold. Players tend to vote for the two or three options they like most, instead of all the options they approve of, yet an omission is still treated as a vote against in most circumstances.)
[X] Are there any additional Guilds that they'd recommend actively avoiding?
[X] Does Lion's Pride have infighting or other political nonsense among their different sub-factions?
[X] Can they go into more detail about Liquid Horizon and Sylph Symphony? Compare between them, benefits of joining and why would someone study lost magic over magic tools, or vice-versa.
[X] Do they happen to know what the general reception for Warlocks has been? There's a big difference between 'legal' and 'accepted.'
[X] Are there any moral Warlock Guilds around, or is that still thought to be an oxymoron?
[X] Could they tell you anything about the sorts of entities who spout ominous poetry within dreams, or refer you to people who might know more?
The only question with a potential drawback is mentioning the dream entities, but I think it's worth including anyway. In a medieval society, news and rumors travel slowly — at minimum, it'll be several days or weeks before any info we give these guys can spread to nearby towns. In practice, they probably won't be inclined to spread rumors about Blake until and unless she becomes somewhat famous. A random cat-eared wizard asking about ominous voices in dreams is
weird, and might make them a little wary of her, but it's hardly a juicy piece of gossip. Blake's just not that big of a deal.
"Anyway, I don't think anyone would object if I started with Lion's Pride; they're possibly one of the largest Guilds on the entire continent and contain a number of sub-factions easily large enough to form their own Guilds. You've got those seeking Lost Magic, paladins mostly motivated by altruism, battle junkies, explorers, treasure hunters, wealth-seekers, scholars, tutors, people just there for the companionship, etcetera. They're based in the capital and have a lot of work because of it, but that also means they complete a lot of work—the highest-paying jobs are likely to be snatched up by someone else long before you see them.
On the subject of Guilds, don't overlook Lion's Pride as an option. For a Planeswalker, the primary selling points of Fairy Tail Guilds are the large variety of magic to observe and copy, and teachers to assist in learning said magic. LP offers the most comprehensive selection of both, and probably the greatest number of powerful wizards among their elite.
"If you want to get into a more exclusive and prestigious Guild at some point, I'd say they're a pretty good place to start. Other Guilds are happy to use Lion's Pride as a proving ground for unknown Wizards, and might extend offers if you impress them on a job or simply get a good enough rep."
"It's also easy to get stuck amid mediocrity," Giuseppe added. "Lion's Pride has some big names, yet there are so many members that they kinda congeal into this huge mass of people. The best Guilds don't really look for members; you have to come to them or catch their eye through luck. My advice would be to join Lion's Pride if you like what they might offer as a large unspecialized Guild. Don't join if you simply intend to join as a footstep toward someone else; that's a ticket to impatience and disappointment."
Blake doesn't need to worry about getting lost amid a sea of mediocrity, either. She's a Planeswalker; it'll quickly become apparent to anyone who sees how quickly she learns magic that she has a ton of potential. She should have little issue finding enthusiastic magic teachers, and it's a good bet that some of the bigger names in the Guild will eventually take an active interest in her progress.
The biggest drawback, perhaps, is how the Guild as a whole might react to a naturally-talented Warlock, and whether Lion's Pride has any skilled ones worth learning from. Angel's Eye may be the superior option, in that regard.
