From reading the note, you get the impression that there is a treasure in an hourglass within the house somewhere. It is very hard to find as there is no real clue in the note as to where it exactly is, and there are 2 normal hourglasses in the house in desks, which may confuse you. However, to find the treasure, go down into the basement, it's embedded in the top of the frame of the wooden pillar with the garlic hanging from it.

Принёс две статуэтки из Culotte и Welke, Умбакано сообщил расположение ещё пяти: Moranda, Mackamentain, Wenyandawik, Nivendava, Fanacas.

Quick List of Where Other Statues Can Be Found:
Culotte:
Find “The Yellow Road” on your map. It’s the road running from The Red Ring Road (around the Imperial City) to the eastern side of Leyawiin. Now, see the “T” in “The Yellow Road”? That’s where this ruin is located.
Fanacas:
Just north of the “Ch” in “Cheydinhal” on your map.
Mackamentain:
There is a small lake located just to the left of the word “Basin” in “The Nibenay Basin”. On the northwestern shore of this lake is your ruin.
Moranda:
Follow The Orange Road from Chorrol to Bruma and when the road takes a dip into the “Fo” of “The Great Forest” you’ll see this ruin.
Ninendava:
If you’ve visited Sancre Tor in the Main Quest, just fast travel there and head east. If you haven’t, head directly northwest from Moranada. Fort Coldcorn is about halfway between this ruin and Moranda so use it as a reference point.
Vilverin:
Remember that ruin on the island across the water when you exited the character creation sewers? This is that ruin. You should’ve exited those sewers just northeast of the Imperial Prison district.
Welke:
There should be a smaller river southwest of the words “Panther River” on your map, follow that body of water up to the actual Panther River and where they meet is where Welke is.
Wendelbek:
If you look at your map, right above the “P” in “Panther River” and right above the “Ri” of the same words are two smaller river systems. You’re interested in the one above the “P”. About halfway between the end of that system and where it meets the main river is Wendelbek.
Wendir:
Find “The Black Road” just south of Chorrol. South from the “c” in “Black” I Wendir.
Wenyandawik:
South of the “R” in the “Road” portion of “The Green Road” which is northwest of Bravil.

When you first exit the Imperial Prison sewers and see the open world, you'll notice an elven ruin across the water from the sewer exit. It is called Vilverin. If you go dungeon crawling deep within Vilverin, you'll eventually come across an ancient Ayleid statue that's worth 250 septims. It's good money for the beginning of the game, so take it and sell it to one of the merchants in Imperial City.

Later, when you leave the city (at least by the gate from the Talos Plaza district), you'll be approached by a messenger. He says that Umbacano wishes to speak with you, hands you a message from Umbacano, and leads you to Umbacano's Manor in the Talos Plaza district. Umbacano is an Altmer of means, who is a collector of ancient Ayleid artifacts. He tells you that the statue you sold (and he acquired from the merchant to whom you sold it) is one of a set of ten that were in the Temple of the Ancestors, which is now known as White Gold Tower. Before the fall of the Temple to the rebellious Cyrodiils the statues were removed for safekeeping. He wishes to acquire the full set of ten, and is willing to pay you double the value (or 500 gold) for each you can bring him. However, he doesn't have any idea where they may be.

To continue this quest, you have to go searching Ayleid ruins until you find another statue. I found one at Wendir, which is located SSW of Chorral, due west of Fort Carmala, and northwest of Hackdirt (assuming you've found the latter two). When you sell it to Umbacano, he tells you that his research has discovered 5 Ayleid settlements where he believes one of the statues was taken. These are Moranda, Mackamentain, Wenyandawick, Ninendava, and Fanacas. Map markers for all of these will appear on your map. You'll have to travel there manually the first time you go.
