An indie Adventure Game created by Crystal Shard. The player takes the role of Maeldun Whiteblade, who is framed for murdering King Vortigern of Theylinn. While on the run trying to clear his name, he has to deal with a goblin invasion, an assassin on the loose, an evil wizard trying to stop him, and the quirky faeries of Thierna na Oge.The game is freeware and can be downloaded here.
Informed Ability - In the opening Info Dump, Maeldun is presented as a great warrior. In the game, he is anything but. Branwyn pointedly explains to the fawning Iseult that Maeldun is their diplomat, and Branwyn herself is the great warrior. She'll show it if you lead the barghest into your camp.
Interface Screw - one of the spells Taranis casts on you inverts the mouse controls.
Invisibility - Maeldun has a spell cast on him so that he will be unnoticable by anyone not strongly connected to the murder. Rhiannon and Geraint are the only ones able to see through the magic, but Iseult and the Chancellor will see if it Maeldun talks too much.
Jerkass - Iseult is a real bitch to someone who isn't wealthy or well-connected.
Lost Forever - There are a few items in chapters 1 and 2 that cannot be retrieved once you end those chapters. There's also several sidequest objectives that can only be done early in the game. Plus, a lot of the inventory objects that can be applied to multiple puzzles are one-use items.
Moon Logic Puzzle - The game's creators definitely tried to avert this, but many instances do crop up, particularly the infamous murder mystery. Some people consider this a Guide Dang It, but the information is all in the game, and through elimination you can figure out that the assassin is really Cailte, in case you wondered.
Not So Different - Lord Geraint and Lady Branwyn, when you think of it. Both command the armies of their master/companion, are completely loyal to them and would do anything they can to protect them. Both are brutally honestdeadpan snarkers to some degree. Branwyn hates Vortigern and Geraint because the latter's armies destroyed here village. Geraint hates Maeldun and Branwyn because the latter's armies vanquished Vortigern's empire. Both cases are mentioned in a conversation between Maeldun and Rhiannon. (Perhaps as a Lampshade Hanging.)
There are at least two to Discworld. You can find "Twurp's Peerage" in the monastery's library, and Maeldun describes cider as a drink made of apples. "Well, mostly apples."
Near the castle, you meet a talking scarecrow.You can give him a brain, and afterward he will name himself Baum.
If you try to enter a stump, a message will appear, requiring you to insert disk 23, followed by 'Oops, wrong game.' Also, on the monk's bed there is a book called 'The Mystery of Ape Atoll,' (no, not THAT Ape Atoll) which involves swordfighting, dark magic and the undead.
The Dev Team Thinks of Everything - You need to buy a flute, and the most obvious ways for getting money are gambling with the goblins, using the wishing well, or selling the sorcerer's figurine. In the unlikely event that you miss the opportunity for all of those, it may seem like you're stuck... but you can still find a pot of gold under the rainbow; if you've already lost that, you can sell Morholt's crystal.
