Cut NPCs in Ultima Underworld

Cut NPCs in Ultima Underworld are four NPCs in Ultima Underworld that were partially coded, before being abandoned and left in the code itself.

Description
There are four different incomplete NPCs that were left in the game code that were supposed to be inaccessable in normal gameplay. However, these can be summoned via the Summon Monster spell, if the casting and mana abilities are at the maximum (though it still takes some luck). This clearly was not intended by the programmers and is an oversight. These four NPCs have their own dialogue, some even with selectable options, and are listen below:


 * A generic mountainman using Ironwit's portrait, who does have a dialogue tree. It's exact same dialogue as all the generic mountainmen found in level 2, all of which use the white-haired portraits.
 * A generic yellow-robed, light-skinned mage with Bronus' portrait. Talking to him the first time, he has four different lines that are randomized. No reply is possible, and after speaking to him his status goes from "mellow" to "friendly". Talking to him again, the dialogue window stays blank and then his status changes to "upset". Summoning other mages is possible, but this one is the only one that talks.
 * A generic ghoul with Kneenibble's portrait. He says the same thing every time when entering the dialogue window; and there are three dialogue options, each with a different response. He then turns hostile, although one can keep talking to him; the dialogue stays the same.
 * A generic dark ghoul with a unique portrait that that is nowhere else seen in the game, as there aren't any dark ghouls in the game that can talk. It has the exact same dialogue and behavior as the generic ghoul.
