The second item in the game is the Sword of Hrakel itself. This item description is slightly more complex in that it references one of the common strings.
2C This is the length of the data describing this item, i.e. 44 bytes
0D Inventory code
01 10 Reference to common string 10, which is "Here lies "
28 Marks the start of the inventory short description
D4 48 45 20 "The "
D3 57 4F 52 44 20 "Sword "
4F 46 20 "of "
C8 52 41 4B 45 4C "Hrakel"
29 Marks the end of the inventory short description
20 47 4C 4F 57 49 4E 47 20 " glowing "
42 52 49 47 48 54 4C 59 2E "brightly."
00 The 00 byte is the end of this item's description data
We saw when looking at the location descriptions that an $01 tells the interpreter that the next code is a reference to a common string. We also decoded and listed what the common strings are and therefore we know that $10 is "Here lies ". The full item description is therefore "Here lies The Sword of Hrakel glowing brightly." and the inventory short description is "The Sword of Hrakel".
We now know enough to fully decode the 33 item descriptions.
01 [0C] A golden wrought ring lies in front of me.
02 [0D] Here lies The Sword of Hrakel glowing brightly.
03 [0E] There is a compass here.
04 [0F] I can see a shelf here.
05 [10] On the ground glints a fine cut gem.
06 [11] An old rusty axe lies nearby.
07 [12] I can see a dull iron bar.
08 [13] I can just see a half hidden bronze key.
09 [13] I've noticed a small silver key here.
0A [14] There is a worn scroll with glyphs on it.
0B [17] There is a bottle of weed-o-kill.
0C [17] There is an empty bottle here.
0D [18] I can see and smell a rotting dead horse.
0E [10] Lying on the ground are shards of a shattered crystal.
0F [19] Nearby is a small study hammer.
10 [1A] There is a wooden raft here.
11 [1B] There is an agitated duck here.
12 [1B] There is a dead duck here.
13 [1C] Stuck in the ground is a shovel.
14 [1D] Spread on the ground is an oval rug.
15 [43] Discarded nearby is a lamp.
16 [43] Discarded nearby is a lit lamp.
17 [00] A rabid wolf bars my way.
18 [00] A wolf's hacked up body lies nearby.
19 [00] There's nasty gargoyles here.
1A [00] Nearby are cindered gargoyles.
1B [00] I can see a meditating guru.
1C [00] The evil mage is readying a spell.
1D [00] A man hangs here in chains.
1E [00] Here lies a man clutching his stomach-moaning.
1F [44] I can see a very large nest.
20 [24] I can see a small silver chest in front of me.
21 [16] There is a pack of matches here.
Up to this point we haven't talked about the second byte in the item descriptions. It is fairly obvious from looking over the values for this byte as shown above that it is related to the inventory. A value of $00 must mean that the item cannot be picked up, whereas two items with the same value must mean they are the same inventory object but in a different state. Examples of the later are the dead duck, empty bottle, and lit lamp. Two items that don't quite agree with this observation are the bronze key and silver key. They both have an inventory code of $13 but surely must not be the same object. I wouldn't know for certain; I haven't finished the game yet!
Sword of Hrakel has 33 items, the data for which starts at offset $04A9:

The item descriptions are stored in a similar way to the location descriptions. As is the case with the location descriptions, a type of compression is used where commonly appearing strings are referenced by code. In addition to this, it marks a smaller snippet of the full description that will be used as the inventory description.
The first item is the golden wrought ring, whose data appears as follows:
2F This is the length of the data describing this item, i.e. 47 bytes
0C Inventory code
28 ( marking the start of the inventory description snippet
C1 20 "A"
47 4F 4C 44 45 4E 20 "golden "
57 52 4F 55 47 48 54 20 "wrought "
52 49 4E 47 "ring"
29 ) marking the end of the inventory description snippet
20 4C 49 45 53 20 " lies "
49 4E 20 "in "
46 52 4F 4E 54 20 "front "
4F 46 20 "of "
4D 45 2E "me."
00 The 00 byte is the end of this item's description data
This is a trivial example in that it doesn't make use of the common strings. It does, however, demonstrate how the inventory description is marked with the opening and closing brackets.
The full description text is used when the item is currently lying in a location. This is demonstrated in the screen shot of the game shown to the left. In this screen shot, the player has just looked in the nest and found something. Whatever it is has fallen out and now appears as an addition to the location description. The player then picks the item up.
When an item is picked up, it is added to the player's inventory. When they type "inventory" or "i" for short, then the items that they are currently carrying will be listed. This list uses the short description of the item, which is the text within the brackets. This is also demonstrated in the screen shot.
